y IMPROVEMENT IN BENDING-MACHINES.

Specification forming part ofLetters Patent No. I02,975, dated Mayl 10, 1870.

.To all whom itmctyconcerb:

Be it known that I, Jol-IN` J. H. SnRcoMBE, of New London, in the county of Waupaca and State of Wisconsin, have invented a new and Improved Wood-Bending Machine, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification, in which- Figure l represents a vertical longitudinal section of my improved wood-bending machine, Fig. 2 is an end elevation ofthe same.

Similar letters of reference indicate corresponding parts.` j j This invention relates to a new machine for bending wood upon a circular bed for the purpose `of making fellies and other articles. The invention consists in the general construction and arrangement of machinery, as hereinafter more fully described.`

A in the drawings 1represents the frame on which my improved machine is arranged. Upon this frame is secured a bed, B, which has a semicircular outer surface, on which the wood is to be bent.

O is a horizontal shaft hung inthe frame A, in the center of the `semicircle formed by the bed vB. Upon the shaft O are mounted, on

both sides of the frame, toothed wheels D D. From each of the wheels D project two vertical standards, E E, that are connected at the upper ends to form the bearings of a horizontal shaft, F, as shown. Between the standl the wheel, so that thus each screw is swiveled.

A bevel-pinion, b, is mounted on the yupper end'of each screw, meshing into a similar pinion, c, on the shaft F. Thus as the shaft F is turned, by means of a suitable crank, d, or other device, the screws will both be turned simultaneously in the same direction and will adj ust the blocks G higher or lower, as may be desired. In the two blocks are the bearings of one or more rollers, I, which can thus, by means of the shaft F, be adj usted any suitable distance from the face of the bed B. J J are pinions meshing into the gear-wheels D, and hung with their arbors in the sides of the frame A. They receive motion by means of cranks e or otherwise, or form other gear-wheels mesh ing into them.

The wood to .be bent is, when the roller Iis brought nearly in a plane with the shaft C, inserted with one end between the roller and the bed B. The roller is then, by means of the shaft F and screws H, adj usted against the outer face of the article to be bent, and then the pinions J are revolved, swinging the Wheels D, with all their attachments, around the shaft C. The roller J, moving parallel with the outer face of the bed B, will lay the wood properly around the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with shaft C and spurwheels D D, of swiveled screws H H, shaft F, and gears b b c c, to adjust the sliding blocks G simultaneously, in the manner described.

2. The revolving wheel D, uprights E, and adjustable roller I, all rigidly connected and moving together, combined with stationary former B, arranged on the frame, as set forth.
